Guide To Galvanized Tube For Mechanical Applications

Galvanized steel is a type of steel with zinc coating. The zinc acts as a corrosion inhibitor, which inhibits the natural attack of moisture on the surface of the steel. Galvanized steel has been widely used in plumbing and pipe fittings because it can withstand moisture and mixtures of acidic substances without corroding for extended periods. In this article, we explain what galvanized tube is, what purposes it serves, and the different types of galvanized tube you might encounter when working with plumbing or other projects that require galvanized tubing.

What is galvanized steel Tube?

The word “galvanized” refers to the process of electroplating (electrochemical deposition) a protective layer of zinc onto a steel substrate. The zinc acts as a corrosion inhibitor, which inhibits the natural attack of moisture on the surface of the steel. Galvanized steel has been widely used in plumbing and pipe fittings because it can withstand moisture and mixtures of acidic substances without corroding for extended periods.

Purposes of galvanized tube

– Structural support – This is one of the most common uses of galvanized pipe, as it makes it possible to construct tall structures like oil derricks and flag poles. – Water or gas transport – Galvanized pipe and tubing are used to transport a variety of substances, including water, natural gas, and sewage. – Electrical conduit – This is another common use of galvanized pipe, as it offers good protection against corrosion, is relatively inexpensive, and is easy to work with. – Piling – Galvanized steel is used as a piling when constructing structures like docks and breakwaters that are subject to waves. – Various construction and agricultural uses – In addition to the above, galvanized pipe and tubing are used for plumbing, scaffolding, and agricultural purposes such as irrigation. – Decoration or soil erosion control – Galvanized steel is also sometimes used to decorate or protect against erosion, particularly on sloping areas.

Galvanized steel tube types

There are two main types of galvanized steel, hot-dipped and electro-galvanized. Both types can be used for all of the above applications. Hot-dipped galvanized steel is the most common type of galvanized steel, and it is created by dipping the steel in molten zinc. Electro-galvanized steel is created by applying an electric current to a steel substrate that has been dissolved in an acid bath. Electro-galvanized steel is stronger than hot-dipped steel. There are several different types of galvanized steel tubing. Round galvanized steel tubing is commonly used for fence posts and agricultural applications, while square galvanized steel tubing is used in construction and agricultural applications.

Galvanized steel tube is a great choice for many applications because it is strong, durable, and affordable. There are many different types of galvanized steel tubing that can be used for a variety of applications.

How to identify galvanized steel tubing

– Look for shiny areas. Galvanized steel has a high-gloss finish (about 10% reflectivity). If a piece of metal is high-gloss, it is likely galvanized steel, especially if it also has a greenish tint. – Look for the letters “Z” or “Zinc” near the edge of the metal. – Look for a silver color. If the steel is blue or black, it is not galvanized. – Look for a stamp indicating the type of steel. – Check the weight of the piece of metal. Typical ASTM steel (not including stainless steel) has a density of about 7850 kg/m3, but galvanized steel is denser, about 8100 kg/m3.

Pros and cons of galvanized tube

Pros – Galvanized steel is relatively inexpensive, widely available, and can be used in a variety of applications. – It can be used in almost any environment where you need to protect against corrosion, including marine environments and those with high levels of acidity. – It is easy to work with, as it is flexible and lightweight, and it can be cut and bent. – The shiny finish of galvanized steel makes it suitable for decorative applications. Cons – Galvanized steel can be difficult to work with in marine environments because it is not as durable against saltwater as stainless steel. – It will corrode if not maintained appropriately. – A highly corrosive environment will require frequent maintenance. – It is not as strong as stainless steel.

Tips for working with galvanized steel tube

– Ensure the surface of the galvanized steel is clean, dry, and free of corrosion. – If you are working with a corrosive substance, make sure to use an appropriate sealing method to prevent corrosion on the inside of the tubing. – Wear appropriate protective gear when working with high-corrosion substances, such as gloves, safety goggles, and long sleeved clothing. – Use the correct tools when cutting, bending, and forming the galvanized steel. – Do not weld galvanized steel, as the heat will damage the zinc coating. – Store galvanized steel in a dry environment, preferably in a dry place with a low level of humidity.

Conclusion

When shopping for galvanized steel tube, you will encounter several different types of tubing. Some of these types have different properties, but they are all suitable for many different applications. In order to select the appropriate type of tube for your application, you will need to be familiar with the different types of galvanized tubing. Once you have identified the type of tubing you need, you can use it for a variety of applications, including water transport, electrical conduit, piling, construction, or agricultural applications. When working with galvanized steel tubing, ensure the surface is clean and free of corrosion, wear appropriate protective gear, use the correct tools, store the tubing in a dry environment, and clean it regularly to prevent corrosion.
